FLOOR-POLISHING ATTACHMENT FOR VACUUM CLEANERS.

Application filed Jul 22, 1925. Serial No. 45,243.

The object of this invention is to provide an attachment for polishingfloors that is adapted to be placed ona vacuum cleaner and to beoperated in connection therewith anal removed therefrom when not in use.

This and other objects of the invention will be fully illustrated int-hedrawings, described in the specification and pointed out in the claimsat the end thereof.

In the drawing:

Figure 1 is a side elevation of a standard make of vacuum cleaner towhich has been added my floor polishing attachment.

Figure 2 is a top plap view of the combination shown in Figure 1.

In the drawings like reference numerals indicate like parts.

In the drawings, reference numeral 1 indicates a'vacuum cleaner which isprovided,

with a housing 2, The apparatus is supported on four wheels, 3 and 4,and 5 and 6. Reference numeral 7 indicates the shaft that is driven bythe electric motor that furnishes power to the vacuum cleaner. On thisshaft is provided a small pulley 8 which is: driven by the electricmotor 9. A handle 10 is provided pivoted on the housing by which theapparatus may be conveniently moved around from place to place.

The floor polishing device comprises the disc 11. This disc is keyed tothe shaft 12 that is adapted to rotate in the boss or bearing 13 that issupported on a member 16 in a bracket 14 which in turn is clamped to andsupported from the casing of the motor which drives the vacuum cleaner.To provide adjustment and ease of attachment and removal this bracket iscomposed of several parts which will now be described as follows: I

A strap 15 is provided which surrounds the casing of the motor and theends of.

which extend forward therefrom parallel to each other. Between theseends is engaged a member 16 which is formed preferably as a casting andwhich has the boss or bearing 13 formed thereon and above the boss 13 ithas an enlarged head 13 containing a circular recess therein. The shankof the member 16 has parallel sides and the rear end of it is of reducedthickness and engages between the parallel ends of the strap 15. Thebraces 18 and 19 are also provided which braces are attached to the andthe vacuum cleaner.

strap at the rear end and are clamped to the shank of the member 16 atthe forward end. The shank 16 is provided with slots as indicated at 20and 21. The bolt 22 passes through the slot 20 and through the forwardends of the braces 18 and 19 and clamp the braces to the shank 16. Thebolts 23 and 24 pass through the parallel ends of the straps 15 andthrough the slot 21 in the reduced end of the shank and clamp the shankto the strap. The bolt and thumb nut 25 passes through the strap closeto the casing of the motor and by turning the thumb nut the strap isclamped to'the casing of the motor so as to make the bracket and theattachment rigid with the motor By turning the thumb nut in the oppositedirection the strap is released and springs away from the casing. of themotor sothat the attachmentcan be removed.

The disc 11 is provided with a polishing pad on the under side. On topit is provided with a hub 30 which is provided with an annular groove inwhich the belt 31 runs, which belt is driven by the pulley 8 on theshaft 7 of the motor so that the rotation of the motor causes thepolishing disc to turn. The shaft 12 rotates in ball bearings 32 and 33and has a collar 34 at the top thereof. On top of this collar is a ballbearing which turnsagainst a plate 35 which is held down by the spring36 on which tension is placed by theadjusting screw 37. This arrangementforms a thrust bearing that permits the shaft 12 torise and fallinits-bearing a little so that the polishing surface of the disc 11 cancome firmly and accurately into contact with the floor'on which it iswnrking and is held yieldingly in place thereon or in working contacttherewith.

The polishing attachment forming the subject matter of this invention isespecially adapted for use in polishing fioors after they havepreviously been waxed. The wax is applied to the floor in the usualmanner after a clamping device at one end of said bracket adapted to beclamped to the frame of a vacuum cleaner, an adjustable extensionprovided on said bracket, a vertical bearing formed at the outer end ofsaid extension, a shaft mounted in said vertical bearing, a polishingdisc provided on said shaft, a pulley for rotating said shaft and meansfor rotatingsaid pulley and said disc on the operation of said vacuumclener.

2. A detachable polishing attachment for vacuum cleaners which comprisesa bracket, a clamping device at one end of said bracket adapted to beclamped to the frame of a vacuum cleaner, an adjustable extensionprovided on said bracket, a vertical bearing formed at the outer end ofsaid extension, a shaft mounted in said vertical bearing, a polishingdisc provided on said shaft, a pulley for rotating said shaft and meansfor rotating said pulley, and said disc on the operation of said vacuumcleaner, 2. pair of braces connecting said clamping means with saidextension to hold said extension ailgid during the rotation of saidpolishing In testimony whereof I afiix my signature.
